Vert rarely seen or offered, and exceedingly beautiful, "Blue-eyed Mary" is one of the most desirable spring plants. Sprays of bright blue flowers on darker stems open from earliest spring to early summer, over a slowly creeping, but staying compact, semi evergreen carpet of shiny leaves.

It is well established in the grounds of Highlands College, Jersey, where it may be a garden escape, and also in West Kent in the UK. ... Learn More
